DETERMINING THE EXHAUSTION OF PROFESSIONAL SOCCER PLAYERS AFTER LONG AND HIGH-INTENSITY EFFORTS BY MEASURING THE FORCE AND BLOOD LACTATE
This study was done on 19 professional soccer players who are playing on the Football Team of Karşıyaka-Turkey`s II. Professional League. The average age is 21.5±4.27, the average body weight is 72.3±7.06 kg, and the average height is 179.6±5.11 cm. In the study; body fat ratio percentage (%) was 13.45±2.50, vertical jump 62.0±6.76(cm), anaerobic capacity according to Lewis nomogram 125.68±15.46 kg.m/sn, aerobic capacity (VO2max) 55.10±4.09ml/kg/min, flexibility 16.34±5.23 (cm). The Wingate Anaerobic Power test (30 sec) was done three times and the rest interval was 2 minutes between each workout. At the blood lactate measurements, the blood samples were taken after each workout the lactate measurements were done at the 3rd and 5th minutes. 20-meter Shuttle Run Test was done to calculate the VO2max indirectory. In conclusion to add of all this; we found a correlation between these parameters; fatigue index (%) with blood lactate mean values at the second measurement, anaerobic capacity with body weight and vertical jump mean values, fatigue index with minimum power/kg and peak power/kg mean values. And we found differences between the three peak power/kg and average power/kg. Minimum power/kg, fatigue index (%), and the four blood lactate mean values.
